慢性阻塞性肺疾病(COPD)是一种以气流不完全可逆受限并呈进行性发展为特征的疾病,在全球范围内是引起死亡和功能致残的主要疾病之一。对COPD患者进行活动耐力评估,有助于了解患者的肺功能损害程度、机体的功能状态与生活质量水平,预测预后。6min步行试验(6MWT)作为一种操作简便、安全、实用,接近日常生活实际的运动试验,逐渐广泛应用于评价中、重度心肺疾病患者的活动耐力。本文就6MWT的测试方法与注意事项,在COPD中的应用及其可重复性与有效性、局限性、研究进展做一综述。
Chronic obstructive pulmonary disease (COPD) is a disease characterized by incompletely reversible airflow limitation and progressive development, and is one of the leading causes of death and disability in the world. Assessment of endurance exercise in patients with COPD can help to understand the degree of lung dysfunction, the functional status of the body and quality of life, predict prognosis. 6min walk test (6MWT) as a simple, safe, practical, close to the actual daily exercise test, gradually widely used in the evaluation of patients with moderate and severe cardiorespiratory disease endurance. In this paper, 6MWT test methods and precautions, the application in COPD and its repeatability and effectiveness, limitations, research progress is reviewed.
